Tablet Holding Device with Upstanding Walls and Ridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tablet computer holding devices do not provide adequate gripping surfaces around the perimeter, leading to discomfort and increased risk of dropping the device when held for extended periods, as they primarily focus on impact or scratch protection rather than facilitating secure grasping.
Innovation Solution
A tablet computer holding device with a rigid, rectangular base featuring upstanding walls and elongated ridges on the perimeter and bottom surface, along with fasteners like clips for secure attachment, allowing for comfortable gripping and orientation-independent use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional protective cases are used, then impact protection and scratch protection are provided, but gripping surface and ease of holding are not improved
Solution Approach 1:
The protective case is segmented into distinct functional zones: smooth protective surfaces for impact/scratch protection, and textured gripping zones with raised patterns specifically designed for finger contact. This segmentation allows each zone to optimize its specific function without compromising the other.
Solution Approach 2:
Different surface qualities are applied to different locations on the case. The gripping areas feature textured patterns with increased friction coefficients, while other areas maintain smooth surfaces for aesthetic and protective purposes. This local differentiation resolves the contradiction by providing enhanced gripping exactly where needed.
2Object-affected harmful factors
If tablet is held by edges to avoid touching screen, then screen protection is maintained, but firm grip and prevention of dropping are compromised
Solution Approach 1:
The case acts as an intermediary between the user's hand and the tablet. The textured gripping surfaces provide the necessary friction and contact points for a secure hold, while the case structure prevents direct finger contact with the tablet screen, thus protecting it from unintentional touches.
Solution Approach 2:
The gripping surfaces extend vertically along the edges of the case, creating additional gripping dimension. This vertical extension provides finger contact points that wrap around the tablet's perimeter, enhancing grip security without requiring contact with the front screen surface.
3Ease of operation
If holding tablet for extended period, then portability and convenience are achieved, but user fatigue increases
Solution Approach 1:
The gripping surfaces incorporate curved and contoured patterns that conform to the natural shape of human fingers. These ergonomic curves distribute pressure more evenly across the hand, reducing fatigue points and enabling comfortable extended holding periods.
Solution Approach 2:
The surface texture parameters (friction coefficient, pattern depth, spacing) are optimized to maximize grip security while minimizing the force required to maintain hold. This reduces muscle exertion and delays the onset of fatigue during extended use.

AI summary
A tablet computer holding device having a rigid and substantially rectangular base is provided. A pair of upstanding walls extends vertically upward from the perimeter of the base and partially bound the base. The upstanding walls provide a widened area for a user to grip. The upstanding walls extend along a pair of opposing sides of the holding device and wrap around the corners thereof, such that the upstanding walls resemble a pair of opposing U-shapes. Since the upstanding walls do not extend around the entire base, inputs and buttons disposed on the sides of the tablet computer can be easily accessed. A plurality of elongated ridges is disposed about the perimeter of the holding device to facilitate grasping the holding device. One or more fasteners, such as clips, are disposed on the periphery of the base and are used to securely hold a tablet computer in place thereon.
